PHOTOVOLTAIC CELL• Photovoltaic is the direct conversion of light into

electricity at the atomic level.• A photovoltaic cell(PV) is a device that converts sun

light into direct current through photoelectric effect. • Photovoltaic cells are made of semiconductor devices.

8

DC- DC CONVERTOR

• DC- DC Convertors used for the purpose to a get a controlled DC output . It converts the uncontrolled DC to controlled DC.

• The convertor used is current - fed type:- current –fed push pull convertor. current – fed power convertor.

ADVANTAGES OF CURRENT- FED CONVERTORS

• No fast rising current spikes created.• Do not causes magnetic core

saturation under erroneous condition.

• As SCR based power supply i.e. it is more robust

10

• Controlled output DC is obtained• No need of filter capacitor at input• This topology can also be derived from

boost convertors by inserting a transformer.

INVERTER

• Power electronic device which convert DC to AC.

• Three phase six pulse inverter used.

• A power inverter can be entirely electronic or may be a combination of mechanical effects.

• Inversion is done by the help of transistors.

CONCLUSION

The DC power so obtained from solar power photovoltaic cell is fed to CFPP converter and controlled DC so obtained is inverted by three phase six pulse inverter in order to integrate three phase electric motor for various applications.
